The movie camera, film camera or cine-camera is a type of photographic camera which takes a rapid sequence of photographs on an image sensor strips of film. Since 2010's, film-based movie cameras have been mostly replaced by digital movie cameras in areas of home, television as well as cinema. In contrast to a still camera, which captures a single snapshot at a time, the movie camera takes a series of images; each image constitutes a "frame". This is accomplished through an intermittent mechanism. The frames are later played back in a movie projector at a specific speed, called the frame rate (number of frames per second). While viewing, a person's eyes and brain merge the separate pictures together to create the illusion of motion.
